This is the second time I have made it and is it supposed to stay gooey in the middle with a firm crust on top? Even after completely cooling the middle is still goody. Tastes very good but awfully sticky in the center!

I double checked my recipe and that was the right amount of sugar. They did come out a bit soft in the center but it set up when they cooled a bit, of course at my house they were nibbling at the edges while they were still warm.
